<p>Seeks a station up or down. </p>
<p>Seek up or down a station and call a function defined by the developer to show the frequency and stop seeking process by the user.</p>
<p>The first parameter of this function is a name of your function that you have to implement to show the current frequency.</p>
<p>The second parameter is the name function that will check stop seeking action. Thus function should return true or false and should read a button, encoder or some status to make decision to stop or keep seeking.</p>
<p>If you do not want to show the seeking progress, you can set NULL instead the name of the function.</p>
<p>If you do not want stop seeking checking, you can set NULL instead the name of a function.</p>
<p>The code below shows an example using ta function the shows the current frequency on he Serial Monitor. You might want to implement a function that shows the frequency on your display device.</p>
<p>Also, you have to declare the frequency parameter that will be used by the function to show the frequency value.</p>
